test_cpp_extensions_jit tests are failing because of missing cudnn.h header file on main branch

Tests Failing:
test_jit_cudnn_extension

Env details:
PyTorch version: 2.10.0
Branch: main
OS: RHEL 9.6
CPU: Intel
python version: 3.12
commit id : 6de6685797cabc6256df76803f3a5f772d5275a7 (tag: trunk/6de6685797cabc6256df76803f3a5f772d5275a7, origin/main, origin/HEAD)

Steps to repro:
1. Log in to H200.
2. Login to quay.io: podman login quay.io
3. Pull base image: podman pull quay.io/aipcc/pytorch:rhel9_6_pytorch_main_gitd766976_cuda12_8
4. Run the image and specify the GPU to be used: podman run -it <IMAGE_NAME>
5. Run the PyTorch UT: TEST_CONFIG=cpu python3 test/run_test.py -i test_cpp_extensions_jit -k test_jit_cudnn_extension

Expected result: UTs should run fine.
Actual result: Missing cudnn.h header file causing compilation failure, which leads to RuntimeError when building the extension and ImportError when trying to load the shared object file
